Material Safety Data Sheet - Heico Wire Group

1 Material Safety data Sheet Updated March 2010 1 of 3 Section 1 - product Identification product Name: zinc Galvanized Steel Wire Products This MSDS covers all zinc Galvanized Steel Wire Products manufactured by Davis Wire Corporation production facilities located at: Davis Wire, Pueblo Davis Wire, Kent 2100 South Freeway, Bldg. 14 19411 80th Avenue South Pueblo, CO 81005 Kent, WA 98032 (719) 566-3960 x 118 (253) 867-1270 Section 2 - Hazard Identification Steel products in their sold state present no inhalation, ingestion, or contact hazard.

2 Operations such as burning, welding, sawing, brazing, grinding, and machining, which result in the generation of airborne particulates, may present hazards to the respiratory system. SHORT-TERM (ACUTE) EXPOSURE: Excessive inhalation of metallic fumes and dusts may result in irritation of eyes, nose and throat. High concentrations of fumes of iron-oxide, zinc , lead and manganese may result in metal fume fever. Metal Fume Fever is characterized by chills, fever, vomiting, irritation of throat, upset stomach, and body aches and siderosis. LONG-TERM (CHRONIC) EXPOSURE: Chronic and prolonged inhalation of high concentration of fumes or dust may lead to the following conditions: Iron-Oxide = Benign pneumoconiosis with X-ray shadows indistinguishable from fibrotic pneumoconiosis (siderosis).

3 Lead = Anemia, urinary dysfunction, weakness, constipation, nausea, nervous disorder. Lead is listed as a Group 2B possible human carcinogen by IARC. zinc Oxide= May cause metal fume fever. Gastrointestinal inflammation reported in animal studies. Manganese = Bronchitis, pneumonitis, and lack of coordination. Nickel = Lesions of the skin and mucos membranes, possible cancer of the nose and lungs-Bronchogenic Carcinoma. Nickel is listed as a Group 2B possible human carcinogen by IARC. Section 3 Hazardous Composition Information product Name zinc Galvanized Steel Wire Ingredient CAS No. PEL 1 TLV 2 REL 3 STEL 4 IDLH 5 Iron Oxide Fume (as Fe2O3) 1309-37-1 2500 zinc Oxide (ZnO) 1314-13-2 500 Lead (Pb) 7439-92-1 100 Manganese Fume (Mn) 7439-96-5 (C) 6 500 Nickel (Ni) 7440-02-0 10 Notes: All values are in mg/m3.

4 Section 4 First Aid Measures EMERGENCY AND FIRST AID MEASURES: Remove from exposure and obtain medical attention. If victim is unconscious, administer oxygen. If not breathing, resuscitate immediately. If flu-like symptoms (cough, muscle pain, fever, chills, insomnia, or mental confusion) develop after use, obtain medical help immediately. Section 5 - Fire and Explosion Hazard data Flammability: This Material is not flammable or combustible. National Fire Protection Association (NFPA) Rating: Health - 1 Flammability - 0 Reactivity 0 Fe Zn Pb Mn Ni 95% - - > > Davis Wire Corporation Material Safety data Sheet product Name: zinc Galvanized Steel Wire Date: March 2010 2 of 3 Section 6 - Spill or Leak Procedure Spill of Leak Procedure: Not Applicable Section 7 - Handling and Storage Precautions: None Section 8 - Exposure Controls & Personal Protection No inhalation exposures unless performing welding, cutting, or grinding this product .

5 If performing welding, cutting or grinding then: VENTILATION: Use enough ventilation and/or local exhaust to keep fumes and gasses from you breathing zone and below all published exposure limits (See Section 3). To avoid exposure to metal fumes additional ventilation may be needed when welding on coated metals, such as painted, galvanized, or plated parts. Proper use of an appropriate respirator may be necessary when welding in a confined space, or if ventilation is inadequate. Train the welder to keep his head out of the fumes. RESPIRATORY PROTECTION: For protection against Iron Oxide Particulate use air purifying respirator. Additional respiratory protection may be necessary. Employer should ensure employee exposures are below all published exposure levels for those substances identified in Section 3 of this MSDS.

6 EYE PROTECTION: Always wear Safety glasses when sawing, brazing, grinding, or machining. Wear welding helmet or use face shield with filter lens, Shade No. 10 or darker when welding. PROTECTIVE CLOTHING: Wear hand, head and body protection to prevent injury from cuts, scraps and wire pokes. See OSHA Safety and Health Standards, available from the Government Printing Office, Superintendent of Documents, Box 371954, Pittsburgh, PA 15250-7954, or at ( ). Section 9 - Physical and Chemical Properties zinc Galvanized Steel Wire products are solid metal, shaped as wire of various diameters. Density: lbs/ft3 Melting Point: 2700 oF Section 10 - Stability & Reactivity Information Materials to Avoid: Avoid contact with calcium hypochlorite, mineral acids, and oxidizing agents which may generate hydrogen gas.

7 Stability Condition to Avoid: None Hazardous Polymerization: Will Not Occur Hazardous Decomposition Products: Steel wire will decompose to produce Iron Oxide (Rust). Welders are exposed to a range of fumes and gases. Fume particles contain a wide variety of oxides and salts of metals and other compounds, which are produced mainly from electrodes, filler wire and flux materials. Ozone is formed during most electric arc welding, and exposures can be high in comparison to the exposure limit. Oxides of nitrogen are found during manual metal arc welding and particularly during gas welding. Section 11 - Toxicological Information Nickel (Ni) and Lead (Pb) are listed as Group 2B, possible human Carcinogens by IARC. Canadian WHMIS Class D, Division 2B (Toxic).

8 Section 12 - Ecological Information Ecological Information: Not Applicable Section 13 - Disposal Considerations Waste Disposal Methods: Prevent waste from contaminating surrounding environment, scrap steel should be recycled. Discard any product , residue, disposable container, or liner in an environmentally acceptable manor, in full compliance with federal state and local regulations. Lead is a listed hazardous waste.
